Not sure what to tell you on the incubators. Those are not names I know. I use an old, styrofoam Little Giant with an egg turner. I have been pretty successful with the cheap ($60) styrofoam incubator but I purchased an external thermostat to use with it. This is the one I purchased:

Most incubators work on timers not thermostats. As a result, if your room changes temperature or your babies generate heat at the end incubation, the temperature in the incubator changes too much.
I would suggest getting a good hygrometer to measure humidity. Too high humidity can cause as many, if not more, problems, as low. You might want to read about "dry" incubating.
